7. Service and MaintenanceSafety Shut Off SwitchThe automatic shut off chain is for safety. It is designed to shut off the electrical power to the unit shouldthe trolley or swivel unit bind up, preventing normal travel of the Stir-Ator. To properly attach, hook thechain end with the open loop to the “S” hook welded to the suspension bar. Hook the other end of the chainonto the “S” hook in the switch box handle.Use the “S” hook on the end of the shut off chain to hook any excess chain slack back on to the chain itself.This allows the length of the shut off chain to be adjusted at the switch box.Design III Stir-AtorFigure 7FWith the unit running, there should only be enough slack in the chain so that the switch box handle is notpulled down during normal operation. Too much slack in the chain will fail to shut the unit off if there is aproblem and could get caught in the machine itself as the Stir-Ator passes under the shut off chain. Securethe shut off chain and the electrical wire above the Stir-Ator with the provided shut off support chain(s).(See Figure 7F.)WARNINGThe electric cord must have more slack than the shut off chain so in the event of ashut off, the electric cord is not ripped from the switch box. This could causeelectrical shock or bodily injury.76 PNEG-1156ETL Design III Series Grain Stir-Ator CSA
